“Turns out you can’t lose the 61 lbs you gained during pregnancy by just scrolling through instragram and wondering why you don’t look like all the bikini models. Thanks @donsaladino for kickin my A double S into shape. 10 months to gain, 14 months to lose. Feeling very proud,” she captioned the above photo.

Saladino has also worked with Lively’s husband, Ryan Reynolds, to whip him into superhero shape for Deadpool and Deadpool 2.

In addition to her 16-month-old, Lively is also mother to 3-year-old James, whom she gave birth to a mere 10 months before shooting surfer flick The Shallows.
